As written it should give you 4 gpu wu's and 1 cpu wu .... with a little bit of cpu left over.

If you want to run 6 total (4 gpu, 2 cpu) then this revision will do it:
<app_config>
<app>
<name>hcc1</name>
<max_concurrent>6</max_concurrent>
<gpu_versions>
<gpu_usage>0.250</gpu_usage>
<cpu_usage>0.50</cpu_usage>
</gpu_versions>
</app>
</app_config>

Hi guys..
I set 1 machine with AMD FX8350 and Zotac Nvidia GTX670 and i use "Auto-setup utility for app_config.xml" method, restart the BOINC manager but my machine still run 1 GPU WU. Are there any specific setting for this kind of combination so i can run multiple WU in that GPU?

Thank you..

edit: i also have another GTX670, i want to trade it to another GPU that will give more PPD, can you guys suggest which one i should get? or do we have link somewhere here with PPD comparison for every GPU.

What version of BOINC are you using? You need 7.0.4+

No link of PPD for ever GPU, as it depends so much on the CPU that it is paired with and the number of WUs running. But the AMD HD78x0 and HD79x0 are particularly awesome in this regard

I've really tried everything for my issue so I decided to extensively explain my problem here so that I may get some help...

-For the past month I have been using BOINC with my CPU only because GPU instantly produces "Computation Error" when a task starts.
-Today I uninstalled and deleted all BOINC files on the PC, including files in programdata. Reinstalled BOINC 7.0.44 and properly set the app config file to:
<app_config>
<app>
<name>hcc1</name>
<max_concurrent>8</max_concurrent>
<gpu_versions>
<gpu_usage>0.125</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_versions>
</app>
</app_config>

After installing BOINC, I opened it, closed it, configured the app_config, then opened BOINC again and got a message saying the "app hcc1 not found in app_config.xml"
Here is what my event log has to say:
Log reports all my PC hardware

and few more of those till slot 15 (note: shouldnt this be restricted "up to 8?")
and then just 1 second later:

and the same thing for all other hcc_1 related tasks
there is nothing else between those lines, just the tasks starting,finishing and output files.

-I am using catalyst 13.2 beta 3 without CCC (I have tried 12.11, 13.1 and with/without CCC installed)
-I attempted to give full read/write permission to BOINC for all users in Programdata
-I have removed all possible restrictions from the BOINC options.

Kiex says in this initial post: "If you get an error about app_name not found in file, check the numbers you entered are correct and perhaps reset the project." But I dont think i've done any mistake here... tried really all i could think of.

OpenCL is unchecked in GPUZ, so I guess there is the failure... lets try to fix that... I always thought that since its an SDK i dont need to install it for programs to to use it.
I could run CPU-based tasks for the past month normally.

You may have to select it while installing the driver or CCC (select custom/advanced install to find it). I missed it a few times on previous setups and it will screw with the gpu units if it's not there

With 4WU's on the GPU each 20% max load, MSI AB reports 95% GPU constant usage.
The most amazing part is that the "Help Conquer Cancer 7.05" takes 4 and a half minutes to finish with 4 of those running at same time.!!!
